batterie charging at 4000

crimson eagle makes the best point..... input versus output. I have tons of packs that will take 3900mah or more but they only put out like 3000mah if i am lucky. They are good for about 3 minutes in modified, after that they flatten out cause the voltage is beat up. Not as big of deal for stock and 19T but still costs you some snap out of the corners.
